46 Clinical Trials for Various Conditions
This healthy related donor clinical trial is linked to a recipient clinical trial protocol for therapeutic purposes. In this healthy donor protocol, haploidentical relatives of a patient with recurrent or metastatic human papilloma virus (R/M HPV) 16-associated malignancy will be invited to be vaccinated with a therapeutic HPV vaccine series (PVX1) to generate HPV-specific white blood cells. In the linked recipient phase 1 clinical trial protocol, patient with incurable, locally recurrent or metastatic HPV 16-associated head and neck cancer will be randomized to one of two arms: Arm A: non-myeloablative (NMA) allogeneic bone marrow transplant (alloBMT) OR Arm B: CD8-depleted donor lymphocyte infusion (DLI) on Day 0 of a dose escalation scheme These two clinical trials are separated so that the healthy donor trial deals exclusively with issues of safety and immunological efficacy of the HPV vaccine series and this companion recipient trial examines the safety, feasibility and clinically efficacy of the allogeneic bone marrow graft and CD8-depleted DLI. The central hypothesis of the clinical trial is that patients with R/M HPV-associated malignancies can be safely and effectively treated by allogeneic bone marrow transplantation and/or CD8-depleted DLI from a healthy related donor that has been vaccinated against HPV16 E6 and E7 proteins.
Multiple retrospective studies suggest that the administration of corticosteroids to treat irAEs is safe, and does not compromise efficacy of ICI therapy in cancer patients. While \~67% of patients respond to corticosteroids, 33% of patients require biologic therapy such as TNFα inhibitors (e.g. infliximab), integrin α4β7 inhibitors (e.g. vedolizumab), or JAK/STAT inhibitors (e.g. tofactinib). This study aims to determine that distinct pathobionts govern the development of irCAE and IMC; and that the administration of hdFMT may reverse steroid-refractory irCAEs or IMC. The use of hdFMT has been shown to be effective in steroid and biologic (TNFα and/or integrin α₄β₇ inhibitor) refractory colitis in PD-1 and/or CTLA-4 ICI treated cancer patients in single-institution case series.
In this is a randomized phase II study the addition of hd-FMT (healthy donor fecal-microbiota transplant) to pembrolizumab /lenvatinib in PD-1 R/R melanoma will be evaluated over a 104-week period in patients with anti-PD-1 R/R disease. Patients with PD-1 refractory advanced melanoma are eligible to enroll, excluding patients with prior lenvatinib (or other TKI) exposure. Intestinal microbiome composition mediates response to anti-PD-1 by affecting systemic inflammatory tone.
This study is to determine if Healthy Donor FMT (hdFMT) improves the body's ability to fight cancer in patients with relapsed/refractory PD-L1 Positive NSCLC.
1. Primary Objective To determine the safety and tolerability of 12 once monthly transfusions of GMFFP (Granulocyte - Colony Stimulating Factor (G-CSF) Mobilized Fresh Frozen Plasma harvested from young, healthy donors), given to older, frail individuals who are at risk due to unhealthy aging and who will then have a subsequent 12-month follow-up period. 2. Secondary Objective To determine the efficacy in older, frail individuals of 12 once monthly transfusions of GMFFP (Granulocyte - Colony Stimulating Factor (G-CSF) Mobilized Fresh Frozen Plasma harvested from young, healthy donors), and a subsequent 12-month follow-up period, to improve the Immune Risk Profile, ("IRP"), cognitive function (MME), quality of life (OPQOL-35), Frailty Index ("FI"), associated with unhealthy aging in the treated subjects.
Background: - White blood cells called granulocytes help the body fight infection. People who have had chemotherapy or bone marrow transplants may have very low numbers of these cells. Transfusions of these cells can help improve the body's ability to fight infection. However, most of the cells are located in the bone marrow or spleen, and are hard to collect from healthy donors. Two drugs, filgrastim and dexamethasone, can help move the cells to the bloodstream to be collected by apheresis. Researchers want to study the best ways to collect these white blood cells. They also want to monitor the effects of the injections and donations on the volunteer donors. Objectives: - To improve the amount and quality of granulocytes (white blood cells) collected by apheresis for donation. Eligibility: - Healthy volunteers between 18 and 75 years of age. Design: * Participants will be screened with a physical exam and medical history. Initial blood tests will be done to check for eligibility. * Participants will donate granulocytes by apheresis a maximum of 12 times in 1 year. Donations will not usually be requested more often than every 4 weeks. Donors will be allowed to decline participation at any time. * Participants will have one injection of filgrastim 12 to 24 hours before donation. They will also have two tablets of dexamethasone 12 hours before donation. * White blood cells will be collected through apheresis. The apheresis will last about 2 hours. * Participants will be eligible to donate until they reach their 76th birthday....
Background \& Rationale: About 75% of US population living today will not die of cancer. There has been a recent report of a colony of cancer-resistant mice developed from a single male mouse that unexpectedly survived challenges of lethal cancer cell injections. In these so-called spontaneous regression/complete resistant (SR/CR) mice, cancer cells are killed by rapid infiltration of leukocytes, mainly of innate immunity. This highly effective natural cancer immunity is inherited and mediated entirely by white blood cells. Moreover, this cancer resistance can be transferred to wild type mice through the transfer of various immune cell types including granulocytes. The infusion of white blood cells, particularly cells of innate immunity, is a viable anticancer therapy in humans as well. This proposed trial will test whether white blood cell infusions from healthy unrelated donors can be used to treat cancer. The trial is designed to determine whether responses can be seen in cancer patients after infusion of HLA-mismatched white cells from healthy donors. It is important that the donors and recipients be unrelated and HLA-mismatched to avoid the possibility of transfusion-related Graft vs. Host Disease. The white blood cells from the healthy donors are being collected via apheresis following granulocyte mobilization with dexamethasone and filgrastim. The investigators will refer to the white blood cells as 'granulocytes' because 75-90% of the white blood cells collected through the apheresis will consist of granulocytes. The dose of at least 2x10 to the11th will be given from 4-5 donors at a rate of no more than one donor per day for each recipient. There will only be one infusion per day and no more than 5 infusions per week. Thus, a typical treatment in the study would span 1-2 weeks. After each infusion, the patients will be monitored carefully for possible adverse events. If adverse events occur at any time point during or after individual infusion, the treatment can be stopped until the adverse events can be managed. The daily dose of each infusion is a frequently used level that has a long safety record. The trial will observe the subject's cancer for 3 months after the granulocyte infusions are completed. Response at 90 days will be based on comparison of tumor measurements at baseline. The trial has 3 major endpoints: dose response and tolerance, safety, and efficacy.
Background -NCI-Frederick scientists performing in vitro studies involving human specimens have a need for a reliable and consistent source of samples which protects the donor from research risks. Objective -The purpose of this protocol is to establish a centralized repository for the collection and distribution of samples (either blood, buccal mucosal cells, semen, urine, or nail clippings) from paid, healthy volunteer donors for in vitro research conducted by NIH investigators located at NCI-Frederick and Ft. Detrick. Research will include, but are not limited to, genotype analysis, immune function studies, drug screening, vaccine development, method development, quality control testing of reagents, and propagation of infectious agents, including HIV. Eligibility: Healthy NCI-Frederick employees and other NIH staff located at Ft. Detrick will be recruited. Potential donors will be excluded if screening indicates exposure to HIV, HTLV, Hepatitis C or Hepatitis B virus infection. Study Design: Investigators requesting to participate to the Research Donor Program (RDP) by receiving samples for research use will be required to submit a written memo of request, briefly describing the nature of the research and providing assurance that samples provided through this protocol will be used solely for in vitro research. These Investigators will receive samples that will be either anonymous or coded, depending on the specific need. Codes will be securely maintained and under no circumstances will donor identity be released to Investigators. Donors will receive financial compensation for their time, discomfort and inconvenience according to an established schedule; compensation for blood donation is based on the volume donated.
Increased numbers of white blood cells called eosinophils can cause disease. To investigate this disease, researchers need blood, urine, sputum, stool, cerebrospinal fluid, skin and/or bone marrow samples to compare to samples from patients with this problem. Some of the samples will be used for genetic testing or future research. This study will last for about 10 years and will include a maximum of 50 paid volunteers ages 18 to 65. ...
This protocol is designed to provide a mechanism for the Department of Transfusion Medicine, Clinical Center to collect and process blood components from paid, healthy volunteer donors for distribution to NIH intramural investigators and FDA researchers for in vitro laboratory use. Donors meeting research donor eligibility criteria will be recruited to donate blood and blood components by standard phlebotomy and apheresis techniques. The investigational nature of the studies in which their blood will be used, and the risks and discomforts of the donation process will be carefully explained to the donors, and a signed informed consent document will be obtained. Donors will be compensated according to an established schedule based on the duration and discomfort of the donation. NIH and FDA investigators requesting blood components for research use will be required to submit an electronic (Web-based) memo of request, briefly describing the nature of the research, and providing assurance that samples provided through this protocol will be used solely for in vitro and not for in vivo research. This protocol also provides a detailed schema for careful and frequent laboratory safety monitoring of repeat research apheresis donors. Blood components for research use will be distributed with a unique product number, and the DTM principal and associate investigators will serve as the custodians of the code that links the product with a donor s identity. The nature of the in vitro studies in which the blood and components collected in this study will be used is not the subject of this protocol, and is not possible to describe, since it involves basic investigative efforts in greater than 170 different NIH and FDA laboratories. The intent of this protocol is not to approve the research itself, but to provide adequate and complete informed consent for the donor, and to assure that the education, counseling, and protection of the study subjects (research blood donors) is performed in accordance with IRB, OHSR, OPRR and other applicable Federal regulatory standards...
To test blood samples from volunteer donors of whole blood and blood components using a new investigational test that detects human immunodeficiency virus (HIV) infection. Results will be compared to the current HIV screening assay.
This study involves the collection of blood samples and measurement with the T-TAS PL assay to compare the performance of the T-TAS wS instrument to the T-TAS 01 instrument
This research study tests a new medicine for mobilizing stem cells so they can be collected and used for allogeneic stem cell transplant for treatment of hematological malignancies. MGTA-145, the new medicine, will be given with plerixafor.
Primary Objective: This is a study to investigate the feasibility of harvesting, expanding, and selecting T lymphocytes from cancer patients and healthy volunteers. The preliminary objective of this study is aimed at selecting PD-1+ and CTLA4+ T cells and other cellular fractions from peripheral blood of cancer patients and healthy volunteers by using specific conjugated antibodies, evaluating their functional ex vivo anti-tumor cytotoxicity against targeted autologous tumor cells.
Background: * Bone marrow stem cells, which are found in the bone marrow and blood stream, can be collected and transplanted to treat a variety of types of cancer in a process known as hematopoietic stem cell transplantation (HSCT). When stem cells are taken from one person, most commonly a sibling or a family member, and then given to another person, this is referred to as allogeneic HSCT. Allogeneic HSCT has proven to be an especially effective treatment for patients with some types of cancers of the blood (leukemia) and certain solid tumors. The transplanted stem cells travel to the patient's bone marrow and begin producing normal blood cells, and also attack patients cancer cells. * Because allogenic HSCT does not always prevent the cancer from returning, researchers are interested in determining whether another type of immune cell taken from the stem cell donors white blood cells, called a "natural killer" (NK) cell, can be given in addition to the HSCT to help fight the tumor. In the laboratory, NK cells have been shown to kill tumor cells, but it is not yet know if this will occur when given to patients after HSCT. Objectives: * To determine the safety, effectiveness, and immune system response of giving NK white blood cells to individuals who have received allogeneic HSCT. * To identify possible side effects from the treatment. Eligibility: * Donors: Stem cell donors whose blood matches one of the recipients on six out of six human leukocyte antigen (HLA) (blood immune marker) types. The donor may not be the identical twin of a recipient. * Recipients: Individuals between 4 and 35 years of age who have been diagnosed with pediatric solid tumors that have not responded to standard treatment, or individuals between 4 and 18 years of age who have been diagnosed with leukemia that has not responded to standard treatment. * Other eligibility requirements which include a physical exam and blood laboratory evaluation are included to make sure it is safe for both the donor to donate and the recipient to undergo the transplant procedure. Design: * Donors and recipients will be screened with a full medical history and physical examination, and will provide blood and urine samples; recipients will have tumor imaging studies and other tests as required by the researchers. * Donors: * Participants will receive filgrastim injections (to stimulate the bone marrow) for 1 week to make stem cells travel from bone marrow to blood. * Participants will provide stem cells and NK cells through apheresis. * Recipients: * Participants will have three cycles of chemotherapy to treat the underlying cancer and weaken the immune system so that it will accept the donor cells. * Participants will then receive preparative chemotherapy for the transplant and two days after the last dose of chemotherapy, participants will have allogenic HSCT using the donated stem cells. * Participants will receive an infusion of NK cells on days 7 and 35 after the HSCT. - Participants will remain in the hospital for monitoring after the HSCT and NK cell treatments, and will be followed closely as outpatients for the first 6 months after the transplant and then less frequently for at least 5 years.
Protocol designed to test blood samples from blood donors of whole blood and blood components using a new investigational screening test (PRISM Chagas) that detects antibody to T. cruzi (Chagas infection). Results will be compared to the current T. cruzi antibody screening assay. Specimens positive with the screening assay will be further tested with a new investigational Chagas confirmatory assay \[Enzyme Strip Assay (ESA) Chagas\]. Additional specimens collected under separate protocols or sourced from suppliers will also be provided to the clinical sites for testing with PRISM Chagas assay and ESA Chagas.
The purpose of this protocol is to characterize the performance of CaridianBCT's Spectra Optia Apheresis System, when used to collect mononuclear cells (MNCs) and cluster of differentiation 34 (CD34) positive cells from healthy nonmobilized blood donors and healthy G-CSF (granulocyte colony stimulating factor) mobilized blood donors, respectively.
The purpose of this prospective, randomized, cross-over, multi-center study is to evaluate the performance of the Spectra Optia Apheresis System's CMNC Collection Procedure, compared to the COBE Spectra Apheresis System's MNC Procedure in mobilized healthy donors. Subject safety will be evaluated beginning with mobilization, throughout the collection procedure and for the day following the last collection.
This study will examine the effects of repeated apheresis procedures on bone density and calcium balance. Apheresis is a procedure for collecting large numbers of a specific blood component, such as white cells (leukapheresis) or platelets (plateletpheresis). For the procedure, whole blood is collected through a needle in an arm vein and is directed through a machine that separates it into its components by spinning. The desired cells are removed and the rest of the blood is returned to the donor, either through the same needle or through a needle in the other arm. A blood thinning medicine called citrate is added to the cell-separating machine. Citrate reduces the ionized calcium levels in the blood, which prevents the blood from clotting. When the blood is returned to the donor, the donor also receives the citrate. This lowers the donor's ionized calcium levels which may irritate nerve and muscle cells, causing tingling around the mouth, hands, and feet during the procedure. The reduced ionized calcium levels result in increased parathyroid hormone levels in the donor, can effect bone calcium stores. In addition, some of the citrate that is returned to the donor is excreted in the urine along with calcium, which causes further loss of calcium from the body. It is not known if the calcium loss during apheresis in people who undergo this procedure repeatedly has any long-term effects on body calcium balance and bone calcium stores. This study will measure bone density and calcium balance in long-term platelet and white cell donors and compare the findings with those of whole blood donors, who do not receive citrate. Healthy people between 18 and 80 years of age who weigh between 110 and 300 pounds, do not have a metal prosthesis, and are not pregnant may be eligible for this study. Participants undergo the following procedures: Whole blood donors * Blood sample collection 2 weeks before blood donation. * I removed undergo standard whole blood donation * Urine sample collection. * DEXA scan to assess bone density by measuring bone calcium stores. For this procedure, the subject lies still on a table while the spine, hip, and whole body are scanned using a small amount of radiation. The forearm is also scanned while the subject is seated. The scan may be repeated after 2 years. Plateletpheresis and leukapheresis donors * Standard platelet or white cell donation. * Blood sample collections immediately prior to and after donation, and on the first, fourth, and fourteenth days after donation. * Urine sample collections at the beginning and at the end of the apheresis procedure and on the first, fourth, and fourteenth days after the donation. * DEXA scan at the beginning of the study (no earlier than 2 weeks after their latest apheresis donation). The scan may be repeated after 2 years. * Some apheresis donors may be asked to have a second procedure in which they take calcium according to standard guidelines for plateletpheresis and leukapheresis. During the second procedure, platelet donors will take oral calcium tablets before starting plateletpheresis. White cell donors will receive calcium intravenously (through a vein) during the second leukapheresis. For this second procedure, the donors provide additional blood and urine samples as described above.
The objective of this protocol is to use established standard criteria and methods for the collection of hMSC (human mesenchymal stromal cells) from healthy bone marrow donors. The hMSC collected from the donors will use to develop well-defined and reproducible cell banks. Standard manufacturing procedures and quality control testing methods will be used to characterize and evaluate the final cell product. After the cell banks are created, these cell products will be used in future translational or clinical research.
The PI will study metabolism during liver regeneration in living liver donors
Individuals interested in becoming prospective bone marrow donors and joining the Registry of the National Marrow Donor Program (NMDP) should do so by calling 301-496-0572, the phone number of the NIH Marrow Donor Center. An appointment will be made to have a health history taken and to have a buccal swab collected for tissue (HLA) typing. The current protocol only involves donors already registered with the NMDP, who have been identified as "perfect matches" for an unrelated patient requiring a bone marrow transplant, and who require expedited medical evaluation prior to marrow collection.
To restore immunologic function and virus-free state in HIV-infected patients. Based on previous studies showing temporary improvement in immune function in HIV-infected patients using peripheral lymphocyte transfers and bone marrow transplantation, and based on studies documenting the antiretroviral effects of zidovudine (AZT) and interferon-alfa (IFN-A) as well as the preliminary test tube and patient studies suggesting anti-HIV effects of recombinant CD4-IgG, we propose to treat HIV-infected patients using combination antiretroviral therapy with transplantation of bone marrow and peripheral lymphocytes from previously immunized donors in an attempt to restore immunologic function and a virus-free state.
This randomized clinical trial is studying the side effects of collection of bone marrow from donors treated with or without filgrastim. Giving colony-stimulating factors, such as filgrastim (G-CSF), to donors helps the stem cells move from the bone marrow to the blood so they can be collected and stored.
This phase 2 trial studies how well cluster of differentiation 8 (CD8)+ memory T-cells work as a consolidative therapy following a donor non-myeloablative hematopoietic cell transplant in treating patients with leukemia or lymphoma. Giving total lymphoid irradiation and anti-thymocyte globulin before a donor hematopoietic cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells, such as CD8+ memory T-cells, may boost this effect and may be an effective treatment to kill any cancer cells that may be left in the body (consolidative therapy).
The purpose of the study is to: * Establish and evaluate a system for collection of filgrastim-mobilized peripheral blood stem cells from National Marrow Donor Program donors (NMDP) donors * Assess the safety among NMDP donors of filgrastim administration and PBSC leukapheresis * Assess the safety and efficacy of filgrastim-mobilized PBSC in unrelated donor hematopoietic stem cell transplant recipients * Determine the acceptability of stem cell donation by filgrastim stimulated apheresis in normal donors
More than one site will participate in the collection of blood and urine samples from healthy adult subjects. These samples will be used for future testing to serve as aged-matched normal controls and to establish normal reference ranges in the development of new invitro diagnostic devices.
The goal of this observational study is to learn if PRAT thickness is a marker of visceral obesity and its influence on donors' kidney function and blood pressure in living kidney donors. Population includes male/female, 18 years and up, living kidney donors scheduled for nephrectomy within 6 months, with a BMI of ≤ 27 or \>30, with a PRAT thickness measurement of ≥ 14mm or ≤10mm on CT. The main area it aims to help in, is future care managing blood pressure and obesity in living kidney transplant donors. Primary Hypothesis: We hypothesize that Perirenal Fat Thickness (PRAT) may exhibit expansion, remodeling and inflammation that can negatively affect renal outcomes in LKDs. Researchers will compare PRAT morphology and inflammation in LKDs with low and high PRAT thickness. We will also correlate PRAT thickness with renal outcomes including vascular remodeling, at the time of donation and worsening hypertension and inadequately increased compensatory GFR of the LKD at 4-6 months post-donation. Participants will be separated into one of two groups depending on their PRAT measurement and asked to give samples of their blood, perinephric fat, and urine as research samples. Clinically we will abstract data up to 6 months prior and 6 months after their nephrectomy that includes laboratory findings, CT measurements, vitals, exam data, demographics, medical history and current medications.
This is a single-center study at the Cleveland Clinic Main Campus designed to study biomarkers in healthy individuals to identify novel mechanisms of platelet activation and how platelets drive vascular inflammation and thrombosis in diseases.
